Selectable Caller ID on outbound calls within app

We have local telephone numbers in multiple provinces across Canada. If I am calling a BC customer I should be able to easily select my outbound number display by a dropdown and show my BC number rather than my Toronto number (the same way that I can if I am sending a SMS message). Presently, one has to go into the PBX admin and select the default outbound caller ID - not user friendly for someone who is not an admin or even is an admin and needs to make this change multiple times in a day.
